+Started installing packages on Octave via Octave command line.
+When tried to install stats package:
+<code>
+>> pkg install -forge statistics
+warning: creating installation directory /home/anthony/octave
+warning: called from
+    install at line 30 column 5
+    pkg at line 405 column 9
+error: the following dependencies were unsatisfied:
+   statistics needs io >= 1.0.18
+</code>
+Got this message for this package:
+<code>
+>> pkg install -forge io
+pkg: please install the Debian package "liboctave-dev" to get th
+error: called from '__gripe_missing_component__' in file /usr/sh_.m near line 53, column 3
+</code>
+... so I did this on terminal command line:
+<code>
+sudo apt-get update
+sudo apt-get install liboctave-dev
+</code>
+Which ran without error message.
+Then typed
+<code>
+>> pkg install -forge io
+</code>
+again, and got not error message, but couldn't find any evidence that the io functions exist.  "which" and "help" show that functions aren't there, even after rehashing and restarting Octave.
+Weirdly, I can show this:
+<code>
+>> pkg list
+Package Name  | Version | Installation directory
+--------------+---------+-----------------------
+          io  |   2.4.0 | /home/anthony/octave/io-2.4.0
+</code>
+I searched for help, and this page
+https://www.gnu.org/software/octave/doc/interpreter/Installing-and-Removing-Packages.html
+described an "-auto" flag that loads the packages automatically, so maybe "loading" is an extra step.
+Yep:
+<code>
+>> pkg load all
+</code>
+Does the trick.  I'll have to look up how to load automatically at startup.
+In the meantime, I'll try installing stats package again.
+Will also install econometrics package, because it has MLE functions.
+Had to install optim and struct packages as dependencies first.
